. SPECIFICATION forming part of Letters Patent No. 600,798, dated March15, 1898.

Application filed November 10,1897. Serial No. 658,054. (No model.)

T0 @ZZ whom .it ntcty concern:

Be it known that I, CHARLES PIEZ, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Car-Hauls, of which the following is a specification.

The object of my invention is to so construct a car-haul for inclinedplanes that the breaking of the parts of the mechanism by the cars willbe prevented, as fully described hereinafter.

I-Ieretofore car-haulshave been constructed with independent elevatingand return tracks, each track having a drive-chain with lugs whichengage the cars, so that a car will be elevated by one Vdrive-chain andwill be returned down the inclined plane by another drive-chain, so thatthe car will not run away, but will always be Linder the control of thechains. In shifting the car from one track to another after the load hasbeen discharged the cars have been allowed to run by gravity untilstopped by one of the projections on the chain on the downhaul, and inmany instances these cars come with such force against these lugs as tobreak them or injure the car; and the object of my invention is toprovide mechanism by which the cars Will be carried to thedownhaul-chain, and thus prevent the breakage of the parts.

In the accompanying drawings, Figure l isv a plan view of the upperportion of my improved car-haul, and Fig. 2 is a side view of Fig. 1.

In the drawings I have dispensed with the details of construction, suchas the supporting structure and cross-ties, as theyl form no part of thepresent invention and only tend to confuse the drawings'.

A is the uptrack of the car-haul, and B is the downtrack, and connectedto this downtrack is a track D, having a slight upgrade to the pointwhere it joins the downtrack. This track D is connected to the uptrack Aby the ordinary turnout-section E.

a is the drive-chain, of any suitable construction, in the presentinstance formed of a series of links coupled together by pins, and thisdrive-chain passes over wheels at each end, one at the top of the hauland one at the base, and the top Wheel a. is in the present instance the`driving-wheel. chain is a series of lugs a2, which project a certaindistance, soas to engage with the axle t' of a car I, so that when thecar is run onto the uptrack it will be engaged by one of the lugs andwill be carried up the track to the section A', which has a slightdowngrade to the point of discharge.

Z) is the drive-chain of the downhaul and is adapted to pass aroundwheels ina similar manner to the chain o., and in the present instancethe wheel b is mounted on the driving-shaft b3, driven in any suitablemanner, and on the chain are lugs b2, preferably of the same type as thelugs on the chain d, so that when the car passes onto the downhaul theaxles will come in contact with the lugs and the car will be preventedfrom moving faster than the chain.

The switching-track E is in the present instance on a slight downgrade,so as to allow thecar to travel from the uptrack A to the sectionaltrack D.

d is a drive-chain adapted to suitable carrying-wheels, thecarrying-wheel d' being mounted on the driving-shaft b3, so that thechains b and d will be driven at the same speed. On the chain CZ arepivoted lugs d2, so pivoted that they can move freely forward in thedirection of the arrow 1, Fig. 2. Should a car have momentum enough ontraveling down the inclined track E to strike one of the lugs it wouldsimply tilt it and pass the lug; but its momentum would be checked bythe slight upgrade of the track D, so that the lug on the chain, whichis driven at a uniform speed, will in time move faster-than the car andwill come in contact with the axle and then will carry it forward to thepoint where the track D joins the downtrack B, and I preferably'makethis junction slightly in advance of the point where it would be stoppedby the lugs, so as to give the car sufficient momentum to free itself ofthe one lu g before being stopped by the other; but this momentum is notsufficient to in anyway injure the lug or the car. It will thus be seenthat I am enabled to carry a car up the haul to the point of dischargeand shift it over to the downhaul Without injury to either the mechanismor the car.

On this drive- Y IOO It will be understood that the drive-chain d may bemounted above the car instead of between the tracks, so as to engage acarbody, Without departing from my invention; but I prefer theconstruction shown as being more compact and out of the Way.

I claim as my inventionl. The combination with an inclined plane, of` adownhaul-track, a drive-chain having lugs adapted to engage with a caron the track, means for drivingthe chain at a given speed, whereby thelugs may engage with the car and prevent it from moving faster than thechain, a track-section communicating with the inclined plane and adrive-chain on said tracksection having lugs adapted to engage with thecar on the track so that the car will be moved forward by thedrive-chain to a point Where the track communicates with the downhaul,substantially as described.

2. The combination of the uphaul, a drivechain therefor, the doWnhaul, acarrier-chain therefor, provided with means for engaging a car toprevent its moving faster than the chain, with a track-section inadvance of the downhaul, a drive-chain on said track-section adapted toengage with the car and to carry it over this track-section and to placeit onto the tracks of the downhaul, substantially as described.

3. The combination of the uphaul, the drivechain therefor, having lugsadapted to engage a car and carry it up on the tracks, a downhaul, adrive-chain therefor also having lugs with which the car engages, atrack-section inclined upward toward the point where it connects withthe downhaul, a chain having lugs thereon adapted to engage the car andtraverse it over the section to the downhaul, substantially asdescribed.

4. The combination of the uptrack A, the downtrack B, the interveningsection D having an upgrade to a point where it joins the downtrack B, atrack E having a downgrade to a point where it joins the track D so thata car will be shifted from the uptrack to the track D by gravity, adrive-chain at the track D adapted to'convey the cars along the track Dto the downtrack B, a drive-chain h With which the cars engage on thedowntrack so that the cars will be carried down at a given speed,substantially as described.

5. The combination of the downgrade-track, a drive-chain, lugs thereonadapted to engage the car, an upgrade-track connected to thedowngrade-track, a drive-chain adapted to convey the cars to thedowngrade-track, said chain having pivoted engaging lugs so that the caras it is transferred onto this track, if traveling at a greater speedthan the chain, will tilt the lugs, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence ot two subscribing Witnesses.
